Context
The research record preserves failed approaches when they expose a model boundary, an invalid transfer, or an unsupported strengthening.
Proof or evidence
Lemma R8.1 retains every original arithmetic gate once and permits only identity relays. Gate duplication, recomputation, equal-value sharing, different output SLPs, or a different bilinear algorithm can change the graph and invalidate the per-wire consumer count.
Verification notes
The failure status and preserved lesson are recorded in the cumulative failure ledger.
Limitations
- state copy optimality only for sealed copy-only compilations of the fixed literal expanded DAG.
